Abstract: ABSTRACT OF THE DISCLOSURE         A digital signal is encoded for error correction, and the encoded digital signal is transmitted in M trans-mitting paths.  The signal to be encoded occurs as N sequences of data words.  A plurality n of sequences of error correcting words are generated from respective words of the N sequences delayed by respective different delay times of (D-di) words, where di is a whole number associated with an ith one of the n error correcting word sequences.  The resulting N data word sequences and n error correcting word sequences are provided with respective different total delay times, so that the total delays of the N sequences differ by an integral number D of words from one another. Blocks of the delayed N data sequences and n error correcting word sequences are formed and the blocks are cyclically distributed among the M transmitting paths.  The values of M, W, n, D. and di are selected so that the least common multiple of any two values of (d-di) is greater than (N-n-1)D; and for any value of (D-di), (d-di) and M are relatively prime.  Favorably, M is selected as 2k, and (D-di) is odd.

Abstract: ABSTRACT OF THE DISCLOSURE          A frame synchronizer for detecting synchroni-zing patterns inserted at leading positions of data trains, for each data, which data trains are independent for each period, by a mechanical sensor mounted on the earth observing satellite LANDSAT is disclosed. The code synchronizer comprises a PN (pseudo noise) code generator for cyclically generating a PN code, a comparator and a counter.  A receiving code train including the PN code as a synchronizing signal is applied to the PN code generator and the number of times of coincidence of the output code of the PN generator and an input code is counted.  When the number of times of coin-cidence exceeds a preset number, it is determined that the synchronization has been obtained.  A probability of wrong synchronization is minimized and the loss of image on a ground station is prevented.

Title: Process for displacement washing of porous media
Inventor: LEE PETER F
IPC: D21C9/02
Filed: 1981-09-08
Granted: 1984-08-21
Abstract: ABSTRACT OF THE DISCLOSURE An improved displacement washing process for recovering processing chemicals from a porous medium, particularly wood pulp, is described. The effective mobility of a displacing solution, typically a more dilute solution of the chemical sought to be recovered, is reduced such that it is less than the mobility of the solution to be recovered. In a pulp mill washing system, consumption of wash water may be reduced 0.6 tons of water per ton of pulp produced without reducing chemical recovery. Conversely, chemical effluent from the washer could be reduced by 50% without increasing wash water requirement. Mobility is proportional to the permeability of the porous medium with respect to the solution of interest and inversely proportional to the viscosity of that solution. Mobitity of the wash solution relative to the solution to be displaced is preferrably reduced by the addition of a soluble, high molecular weight polymer, greater than 106, until the ratio of the mobility of the wash solution to that of the chemical rich solution is in the range of 0.05-2.0, preferably within the range of 0.2-1. As examples, copolymers of acrylamide and acrylic acid, carboxypolymethylene, polyacrylic acid and dea?etylated chitin have been found to be effective in reducing mobility. The presence of 6-10 ppm of a copolymer of acrylamide and acrylic acid of MW greater than 106 in the wash solution of a brownstock washer can double the efficiency of the washer.

Abstract: ABSTRACT OF THE DISCLOSURE         A spring clip having a pair of opposing flat holding members the leading ends of which are resiliently pressed against each other to clip sheets of paper or the like therebetween and opposing ear-like projections which extend widthwise from the side edges of the opposing holding member, respectively, and serve to open the leading ends of the holding members in cooperation with opening means of a special device for applicating clips.          In contrast with a conventional spring clip of the same type, the disclosed clip has no levers pivoted to the leading ends of the holding members, which are used to open the leading ends Or the holding members for the purpose of inserting therebetween the sheets to be clipped, and, therefore, is advantageous since the clipped sheets are not prevented by the levers from being turned up.

Abstract: ABSTRACT OF THE DISCLOSURE           A walk-over seat has a base with a pair of side members and a seat back which may be moved between the front and rear ends of the seat.  The seat back is connected to the upper ends of two elongated links on each side of the seat back.  Each link has a lower end mounted for pivotal movement about a horizontal axis between frontwardly and rearwardly extending positions.  Each link is engaged by a respective latching member when the link is in one of its positions.  Structure is provided to transfer to the side members of the seat the load exerted against a latching member by the link when the seat back is impacted or hit from behind, to prevent the latching member from being sprung or bent out of position.  The latching member has a special configuration to accommodate differing dispositions and mountings of the latching member and the link it engages.
